'WINDOlV-SASH DEVICE.

Specification of Letters Patent.

Application filed August 17, 1912. Serial No. 715,602.

To all whom it may concern:

Be it known that I, Crrannns DIrrLn, J12, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Window- Sash Devices, of which the following is a specification.

This invention relates to devices for use in combination with window sashes and primarily relates to means for affording protection against weather which at the same time permit the sash to be reversed for cleaning purposes or to be turned at an angle for ventilation.

The invention permits the sash to turn or swing on a pivot as well as to be locked in a vertical plane and to travel in such plane.

The invention consists in the improved window sash device and in the combination of parts and details of construction hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, Figure 1 is a transverse vertical section through a window frame and the sashes therefor having this invention, in one of its forms, applied thereto. Fig. 2 is a vertical section taken at right angles to that shown in Fig. 3, the section being indicated by the line Y Y in Fig. 3. Fig. 3 is a horizontal section through one side of the window framing and sashes taken on the line X K Fig. 2.

In the drawings, 1 indicates the window frame which may be' of any desired construction or type, while 2 indicates the up per and 3 the lower window sash disposed therein and movable vertically in the plane of the frame to open and close the window. The construction for holding the sashes to the frame is the same on each side of the window so that a description of one will suf tice for both.

Secured to the side of the frame 1 is a stationary shoe 4, preferably C-shaped in crosssection, and rimming vertically the length of the window. Each sash is preferably pro vided with a metal strip 5 secured to the sides thereof, the inner edges of the-strips attached to each sash projecting toward each other and forming a ledge 5.

In one construction to which the invention may be applied, each sash is mounted or hung on a horizontal pivot 6 which in turn is secured in any suitable manner to and suspended by the sash cords 7 operating in the usual Way. The pivots 6'work in suitably formed vertical runways in the side mem bers of the window frame 1.

8 and 9 indicate a pairof U-shaped strips or shoes of metal arranged with their bases apposed to each other so that each spans the edges of the Q-shaped guide shoe 4 and the ledge 5 of the strips 5 whereby the said edges intermesh in the U-shaped part of the strips 8 and 9. The strip 8 is provided to hold the upper sash 2 to the guide l While the strip 9 serves the same purpose with respect to the lower sash 3. Each of the strips 8 and 9 is ofa length approximately equal to or a little longer than its cooperating sash and when in position alongside its sash locks it to the guide and causes that sash to travel in a vertical direction in the plane of the window frame.

Each of the strips 8 and 9 is movable in the guide 4; independent of each other, and the sashes 2 and 3 by means of a knob or button 10 secured to each sash, and when the strip is moved to such a position that the pivot 6 is past the end of the strip the corresponding sash is free to be swung hori- Zontally about the pivot as shown in Fig. 1, the lower sash in this figure being shown in deflected position. Each strip is provided with a spring 11 which bears against the side of the guide 4: and serves to hold the strip in place and prevent rattling. This construction provides a combined sliding and pivoted window and at the same time by means of the intermeshing strips provides a weather proof joint, as any direct opening from one side to the other of the window through the jamb is avoided, and any draft or dust is compelled to take a tortuous course to reach from the outside to the inside of the window. When both strips 8 and 9 are moved to either end of the frame the sashes can be moved to the other end and turned on their pivots thereby obtaining a clear opening nearly the size of the frame, or by merely moving one of the sashes to the other end, it can be completely turned around to permit cleaning the opposite surface of the glass, or can be turned at any angle to get ventilation without direct draft.

It will be understood that the construction shown may be varied within considerable limits, the invention not being limited to the details of construction as shown and described but various modifications might be resorted to and such modifications are intended to be included within the scope of the appended claims.

What I claim as my invention is 1. In a window construction, the combination with the frame, of a vertical guide located at the side of said frame, a pair of U-shaped strips arranged with their bases opposed to each other and freely engaging said guide and horizontally pivoted window sashes each having a part intermeshing with the U-shaped strips, said strips being adapted to be moved longitudinally to free the pivotal mountings of said sashes.

2. In a window construction, the combination with the frame and window sashes hung on horizontal pivots, of a stationary guide located vertically thereof, a pair of oppositely disposed independently movable lei-shaped strips of less length than the 0penmg in the frame and engaging said guide and the window sashes, to hold the sashes to the frame, each U-shaped strip being movable beyond the sash pivot to permit the sash to rotate.

3. In a window construction, the combination with sashes hung on horizontal pivots and the window frame, of a stationary guide secured to said frame and running the length thereof, a plate secured to each window sash and an independent U-shaped strip for each sash adapted to engage said plate and hold it to said guide, each of said strips being movable independently of each other beyond the sash pivot to permit the sash to rotate.

Signed at Brooklyn in the county of Kings and State of New York this 15th day of i-iugust, A. D. 1912.
